Discussion: Maintenance of Project Hamster

Since @tbaugis's priorities have shifted the project is currently unmaintained. I was recently given commit access for a PR and would be willing to take over maintance. Any other interested collaborators are welcome to join the discussion!

Open questions:
- What's the current state of development? (AFAICS the Gtk3 migration is mostly done, and other than the Python 3 upgrade no bigger changes are in progress)
- Who is maintaining the project? (proposal: me if nobody else is interested)
- How should development be handled? (proposal: pull requests for everything)
- Does anybody have experience with Debian packaging? Otherwise I'll look into this myself.
- Who curates the blog at http://projecthamster.wordpress.com/?
- Who updates the extension at https://extensions.gnome.org/extension/425/project-hamster-extension/?
- Are there any other resources contributors should know about?

Pending tasks:
- [ ] update READMEs of all repositories (similar to changes in this PR)
- [ ] update blog about current development status
